We just got a kitten we've had her for 3 days so she is in new surroundings, she's had diarrhea. It was dark brown now it's light. What is causing this? We feed her friskys patte.

Congrats on your new kitten! Lady's diarrhea could be caused by intestinal parasites, a change in diet (if she wasn't fed Frisky's before), a GI illness, or eating something rotten. If she isn't up to date on her deworming treatments, you will need to get one from the vet. You can try a bland diet to see if that helps with the diarrhea. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I would recommend feeing her a high quality kitten formulated food instead of Frisky's. It's not the best quality food, and Lady should be getting kitten food, as she needs more calories, protein, and calcium to support her growth. A kitten food would provide that. I recommend feeding her Royal Canin or Hill's Science diet.
